g The Schedule referred to in these Letters Patent and making part of the same.

To all whom itam-y concern;-

Be it known that I, OsMoRE A. BINGHAM, of Gavendish,'in the county of Windsor and State of Vermont, have invented an Improvement in Chair-Seats; and I do -hereby declare that the following, taken in connection with the drawings which accompany and form part of this specitication, is a description of my invention suiiicient to enable those skilled iu the art to practice it. I

United States Letters Patent N o. 94,553, were granted to me September I, 1869, for an improved chair-seat. In such patented seat the web or iiexible chair-seating is shown as stretched and confined to the seat-frame around its edges, by drawing lsuch edges ot'- the webbing under and around or partially around a strip or strips, which tit into a groove or grooves made iu the top surface of the seat-trame, the strip or strips being pressed into the groove or grooves, carrying the web-edges down into the grooves and tightly confining them, the web edges being carried over the top A ofthe strip or strips, so that the strips are concealed by the web; my invention shown in such patentconsisting particularly in stretching'the web over, or so as to conceal the strips.

My present invention relates particularly to the employment of confining-strips in which the webs are drawn over, and so as to conceal them, though the employment is also applicable to chair-seats having webs contined by the strips, without covering them.

The invention consists in combining with a continuous strip-receiving and web-receiving groove, cut into and extending around the top of the seat-frame, a curved strip or strips, which, extending around the corners or joints of-tlle frame, strengthen said joints, make a better finish than separate strips can make, and are more easily applied.

The drawing represents a chair-seat embodying my improvement.

A denotes a plan of the seat.

B, a section on t-he line x x.

a. denotes the seatfframe, Ywhich may be formed whole (or of one piece of wood) or may be made of two or more strips jointed together, as in common chairseats.

In the top of this frame, near the edge thereof, I sink a deep narrow groove, c, extending entirely around the frame, and curving at the corners, as seen at A, the groove being formed near the inner edgeof the frame.

To tit this groove,Icut a long strip ot' pliable wood, d, to a length corresponding .to the length of the groove, and of a thickness and width slightly less than the width and` depth of the groove. This stripl'steam and bend around a suitable former, to impart to it the shape of the groove.

l then take the chair-webbing e, (made of any suitable chair-seating material,) formed to proper shape,

and draw its edge over the topof the strip around its outer edge and under its bottom edge, (the strip resting upon the top of the frame over the groove,) and having thus drawn the web over the strip I force the strip and overlapping edges of the web down into the groove, thus securing all tightly together. It will be obvious that the continuity of the strip impart-s strength to the frame, especially at the corners, where joints are usually made, or where the grain of `the. wood may run crosswise ofthe frame, and if several strips. are employed, each or either extending around one or more ot' the corners, au analogous result is attained, though I consider the employment of Y one bent and continuous strip preferable to the use of more than one.

It will also be obvious that with my invention the single strip or strips curved around the corners may be employed with a webbing which enters the groove at the inner edge ofthe strip, but I consider a chairseat made with the covered strip to be much neater and in every way preferable.

I claim, in combination with the groove, a strip or strips extending around the corners of the seat-frame from rail to rail thereof, substantially as described.
